you could always save the expense of getting brian the snip, and bring your jills to me, or someone else with "snipped" hobs, to bring them outta season, whilst brian is on his own,
the court looks great, I would however, put a concrete base down, and ask for it to be built without that base on the outside section at least, with 3 ferts wetting onto that, and damp from the floor rising up, its gonna be rotted in no time
my only other worry would be security, as you say, this is all in your front garden, whats to stop someone entering and snipping the wire and making off with ya ferts
